What a great place to see what nature can do and what the earth holds under our feet! Always a spectacular treat so close to nature, great with the family and a fun place to take some funny pics if your creative!

This is a big geyser found in the Upper Geyser Basin. It's located off the paved bike path maybe 1/4 mile from the Old Faithful area on the right side of the path. You can't miss it! It does go off on a regular basis, but we've never been lucky enough to see it in 3 times at Yellowstone. It... More

Another must-see in the Upper Geyser Basin not far from Old Faithful. The Castle Geyser is a cone geyser that truly does resemble a castle. It erupts every 10-12 hours. Get the Yellowstone Geyser App for updated eruption times. Castle has an eruption window of */- 45 minutes. Eruptions last about 20 minutes and are about 100 feet high. This... More

This geyser erupts on a schedule and is located not far from Old Faithful. We watched it erupt at dusk and we're not disappointed. There was a small crowd, you can stand relatively near the geyser, and the display lasts a long time, alternating sprays of water and bellowing steam. Just when you think the eruption is ending, it starts... More

At some point you get geyser'd out. At least this one has a fairly unique look. We did not wait around for it to erupt so I cannot comment on that.

The size of this feature is impressive, considering how slowly they increase through deposits. Really interesting and well worth a few minutes while viewing the other features.

I much preferred castle geysers over Old Faithful. But overall I'd suggest to just take the trail and enjoy all geysers equally.

By chance as we drove past this Geyser it exploded into life. Two minutes later we saw three wolves walking past in the distance which was equally as amazing

This geyser is on the boardwalk that is part of the the Old Faithful geyser viewing area. there are many different types of geysers some that erupt at various different times of the day, months or years, there are signs up with approximate eruption times. Castle geyser actually looks like one due to how the various eruption overlays have solidified... More
